Re: Supermount

2005-07-24 Thread zhilla
well, for a bit of OT discussion sake, here's how it imho SHOULD work, 
from user (noobs and non guru) desktop point of view:
cd/dvds: mounted automatically on insert / first access. if a program is 
running from it (or a file is open from it), and user tries to eject it 
using button, or any eject-like software, kernel sends a signal to a 
central place. which is, for example, picked up from a window manager, 
or even X itself. which, in a friendly and non intrusive way, displays 
something like this: "drive hdc busy, please close the following 
processes first: 1. mplayer 2. blabla".

also, if a blank media is detected on access, it should not be mounted.
usb drives: similar. if user plugs it out without unmounting, its 
unmounted, and processes using files on it gracefully killed, or somehow 
"warned". how to "warn" them? ill let someonbe smarter think of the way 
:) and about ripping it out without closing, wm/anything should yell 
"bad user!! you should ALWAYS unmount first!"
floppys: i suggest leaving things 100% same. btw. i saw some distros 
having problem with accessing ie /mnt/floppy when there is no floppy 
present. bash goes wild with autocompletion. programs pause for a looong 
time. this could be a kernel bug.
other stuff: dont want to sound like troll, but i guess 98% of people 
dont use anything else.
system partitions: make a clear cut between folders which should be seen 
at all by anyone but root, kernel, special software. in other words: 
reduce clutter in / by hiding almost anything! and partition specific 
mount option such as

"userinvisiblefolder=/dev;/sys;/lib;/proc;/sys;/var"
should also be possible. face it, for regular user in varoius distros, / 
is to crowded.
i'm not saying this is all 100% correct or possible. couse this is, 
imho, greatest ugliness, user friendlyness and productivity reducer in 
linux. m$ has it a bit better in some ways, but crappier in other. any 
of these could be a killer feature for 2.8 kernel series. or 2.6.2x :)

i would like people to discuss this. be polite please :)

That's not the only problem.
We can't do owner mounts of the floppy, for example.
smb mounts have similar problems in needing to identify the requester in 
order to get authentication info.

But that's on the agenda to be fixed.

Granted, that can get pretty close. However, having to use /auto/*
instead of mounting directly where required often limits using it quite
a bit. Thus, I don't see it as a real alternative.

To mount on demand use autofs. Unmounting and dealing with media removal

They cannot mount on demand, thus cannot do the same job. The boot
partition, for example, is something that should only be mounted when
required. The same obviously also goes for network filesystems in many
cases (i.e. avoid having zillion idling connections to the server).

I woudldn't care about the implementation (original supermount,
supermountng, submount or something else). Getting the job done is what
counts.

Hi Tronic,

Supermount is obsolete there are other tools in userspace that do the
job perfectly.
e.g ivman which uses hal and dbus.

Including source like supermount because it simply work is not a good
argument. And why to hell should everthing in the kernel, to make
sorry *leazy* people happy? The kernel is not a trash...also
supermount uses ioctl which is nearly removed from kernel?! Please
correct me if i am wrong with ioctl.

Also there are other fs like supermount e.g submount etc...

I used supermount, too - for a long long time...but it cost me a
second to write a bash script with does supermount job's for eject.

Supermount

2005-07-21 Thread Lasse Kärkkäinen / Tronic
Is there a reason why this magnificient piece of software is not already
in the mainline? It seems to be working very well and provides
functionality that simply isn't available otherwise.

For those who are not familiar with it: this system does on-demand
mounting when the mount point is accessed and automatically umounts
afterwards. Unlike autofs, this does not require a special automount
filesystem to be mounted, but the actual filesystems can be directly
mounted where-ever. Also, it "just works" and the CD drive will eject
when the button is pressed, without having to wait for the umount
timeout to pass. I haven't looked inside to find out HOW it actually
does it, because I simply don't care, as long as it just works.

More feature should be added into main kernel(Was: supermount)

2001-06-30 Thread Steve Kieu

Just my humble opinion, please dont laugh if I am
wrong, I think:

Supermount
JFS 

I use the patch from IBM ; now running JFS, and notice
a bit improved performance than Reiserfs, it is good
file system, (they release stable (may be?) release
already). But It is hard, they only give the patch for
the main version, say 2.4.x x< 5 and 2.4.5; I patch to
2.4.5 then apply the ac22 series, it spits errors,
then I had to patch manually but may be I made a
mistake somewhere, when compile it gave me errors, 
Okay some one may tell me to use FOLK, but I tried
last time, and failled to compile, ( I fogot the error
message sorry, ) so now I have to use 2.4.4 with JFS.

The same for supermount, the patch is only for 2.4.0,
but this time I am ok to manually patch it.

i apologise if this is a very silly question or if i have posted

hello, i have only been using linux for about a year, i am a physicist

i have noticed supermount is not a standard part of this project, is
there a good reason why this is? i apologise if this is a very silly
question as i am sure it is, but it really does seem to me to be an
essential feature, are there any plans to include it as a standard
feature or is this due to man-power? i know patches do exist out there
(all beit, really hard to find for recent 2.4.5)

anyways, keep up the good work, i wish i knew enough about the whole

..supermount ? no! (The Ultimate Solution :)

2001-03-24 Thread Gerry

Change the removable device-drivers to detect change. Fx, with cdrom, change 
the cdrom-part to detect when the disc tray ejects and when it goes back in, 
both for manual (user push eject) and automatic (program sends 
eject-request). This way the kernel just have to send a signal when this 
happens on a device (to processes who have requested to get to know).

This has several advantages:

* Supermount don't need to be kernel-related at all, and so doesn't need to 
be updated for each new kernel revision (cleaner kernel)
* Possible to get autorun on linux
* Can get rid of "insert cd and press ok"-like things (replace with "insert 
cd or press cancel")
* Imagination is the only limit :)

So, what do you say ? (I'm a newbie to this, so don't flame me to hard :)

Because it wants rewriting as a clean file system using the 2.4 dcache and
layering itself above the real fs. In theory the infrastructure for this is
all there.

I don't know if this applies to 2.4.2, but there is a patch for 2.4.0:

supermount ?

2001-03-22 Thread Gerry

I recently upgraded my kernel to version 2.4.2, with no problems at all, 
except one: supermount. I guess you already know that supermount haven't been 
upgraded to support 2.4.2 or even 2.4 yet, and i guess there's nothing to do 
about that but wait. But that's not why i'm writing this.

Supermount sounds to me like a very important part of linux, at least for us 
who like our cds/dvds/etc. to work as easily as in fx. windows. For linux to 
be popular among "normal" users, it should be present at every system with 
local removable drives. So, my question is; why isn't supermount a standard 
part of the kernel, or at least a module ?

Right now i have to use autofs to manage automounting, but there's several 
problems with that (as it's aimed at use with network devices): Fx, it locks 
my dvd/cdrw-drives every time they get mounted, so that eject isn't possible 
until it gets unmounted. Floppy disks aren't updated until they're remounted. 
Setting low timeouts doesn't help at this, since it doesn't seem to work that 
well with local devices for some reason..

So, supermount is required even if autofs is included in the kernel, from my 
point of view anyway. I'm sure there's many people out there like me :)

Any chance supermount will be a standard kernel module in the future ?
