Re: systemd hangs on fstab directory bindmount
OK, speaking of gooses, I've discovered the goose is me. I've just spent an hour testing and retesting, trying to recreate the problem! Quite exasperating. So I went back to previous versions of fstab, finally digging up an old internal IDE drive from a previous laptop, to find what I'd somehow changed and hadn't realised I'd changed. So: I use plug-in USB drives here and there (especially when rebuilding/ rescuing my workstation or [re]installing a box). To this end, I create fstab entries on occasion for my USB backup drive, in particular, normally with an auto mount option to speed up my reboot and rescue cycles. My brown paper bag moment (I was evidently not quite as rigorous in my one-change-at-a-time methodology as I thought I was) is my failure to add noauto or comment=systemd.automount to my USB rescue automount. Twice now I've discarded entries in the thought that they were not relevant. This is not so cool, but anyway, problem found. Bit too late now, but I ought to have advised myself to attach a full fstab file, and someone probably would have seen it straight away. Thank you for assisting me on my wild goose chase. I'm now found so we can close this bug... Now, to discover if fstab somehow applies to the ls problem on my eee.

Re: systemd hangs on fstab directory bindmount
PS, This is still just an assumption, as I don't have a photographic memory of every command I ran over the last week, but it's the only way I can recreate something that appears similar/same as I experienced before, so it seems to me, the most likely possibility. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

Re: Bug#693843: systemd hangs on fstab directory bindmount
Is there a ways for this to be slightly less bite-ing for systemd newbies such as myself? Perhaps a timeout of just 20s, plus a big loud syslog msg or something rather than a 2 to 5 minute hang? Just a thought, to assist the impatient who might otherwise be lured into systemd land :) Kind regards Zenaan On 11/22/12, Tollef Fog Heen tfh...@err.no wrote: ]] Zenaan Harkness My brown paper bag moment (I was evidently not quite as rigorous in my one-change-at-a-time methodology as I thought I was) is my failure to add noauto or comment=systemd.automount to my USB rescue automount.

Finally, a workaround - I guess just move my directories manually into place in order to avoid the bindmounts. I think I was doing the bindmounts because at some point my real home was on a different partition. Certainly I don't like the destop of the day trashing my real home. Either way, systemd's hand seems unfortunate. TIA Zenaan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?
