I've encountered the problem in e.g. mythtv - if your DVB adapter takes a long time to initialize (40 seconds for my hauppauge cards, for instance, due to some weird FW loading problem), then your system will just boot and run mythbackend, which won't see any DVB tuners, and none of your scheduled recordings will record. This isn't something that can be fixed outside of MythTV. maybe it's been already fixed upstream, but in 0.25.1 this was still a bug. libudev should provide the methods needed to implement a proper fix.

As Greg already said, there is no point in time where we could send out such an event. If you want, read it as: systemd boots up and enumerates devices until you shut down the system. Such a daemon needs to monitor new devices, build its own list/tree of it, and starts using them when it decides they are ready to be used. For legacy applications, which are too simple to do that, "udevadm settle" is the only tool that can provide something like that. There is nothing in the base OS could claim to be able to send an event for the state of "everything is there" or "there are no more devices to expect", it's just not how things work or should work.

There is no way to ever know that "all plugged in USB devices are enumerated". USB has no such knowledge of this, so wanting to wait for it, would mean you just wait for forever. So you might want to rethink your requirement, unless you like impossible requirements :) > The second one wants to access DVB devices. > > These could be connected via PCI, PCI express or USB.

[systemd-devel] How to wait for a group of devices?
Hello, I need two service files for two daemons. The first one expects some type of device to be accessible via USB. So what I need for this one is something like "Wait until all currently plugged in USB devices are enumerated and the relevant kernel modules have been loaded". The second one wants to access DVB devices. These could be connected via PCI, PCI express or USB. So here I need "Wait until all possible, currently connected, DVB devices are initialized and drivers are loaded". Is there something like that? "udevadm settle" doesn't seem to do the trick. Thank you in advance Yours Manuel ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel

Agreed. Your initial [rd.]crypttab=;;; proposal sounds reasonable. Is ';' a good separator for this (I think it is, just making sure I don't overlook something)? Should the [rd].luks* options be deprecated at the same time? -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.20 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJSEgDEAAoJEChPw0yOSxolVQgP/3hAox/FdrCKi7BMs5rsSe+r NHXnu9nOngBLRHw/DnICQ5HoMAX1HDHLUOdqeWOt4XVI0jn4RDFivzIZnSmpf6QS zi8/oltC38gBd8LyKNfklt3tF6xw5/pfrIBe6DGa6clYywUd9daIsdOXN3sh7yHK InEn3oyfPA4Eno0p5d6hKn4g03KJlsgm313V2Fxr97y6enu2yJjeemlmdOoyMeNf FcUqphobaJWiGYqePEyLJtKoaNq91h6CnLNVQJ8dIIleZeGmCwwpv8xT4A8WyjXQ cRIrDvo7bHMBIHPdFV+UPZ+Crn7OTnJBDTKFJzttnEY8AYI4vpc7kcuTD8yVHxln K/c/NGEuYjO50e26Sso12kFicTXexdXxdELijMZ2MzHpTd6hFeHwa9R5/ts3ZasS AQJLqtVOpJMT2EMnk48JLgOpkgGJiXTs8wC08DMuYP1KjOWa43/EFy1KCHoA6N8G L47meHpIw0EzRgMXtXGBcmFKDbrGZeuX/gxnhAAw17ZO1X0K5sY1Y2FWanc21kqq Zn3PK1OHGlLwiqhblo6hrv0LNRNh1oYJtbQel1DbS60v8Pq3qidsb0IVB8vUuZ8M Zgnjk7N1GgY2DiYkBVjzpvD7og74hK8pf4vvRC/WkmbOsG2VqW1grejzAoF8T1I0 P/f/Zne4C5KGYvBdHhV2 =gtpu -END PGP SIGNATURE- ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel

Now you are proposing to add a > 'crypttab' option as well. This seems awfully inconsistent to me. Well, I think before adding more and more rd.luks parameters, we might want to step back and add one option, which supports all. An object oriented syntax might be: rd.luks..name= rd.luks..options= rd.luks..password= This of course would have made parsing with shell functions unpractical. Now that we already have rd.luks.uuid= adding parameters to results in rd.luks.options== rd.luks.name== rd.luks.password== Both solutions blow up the length of the kernel command line and make it really unreadable. This is why I propose to simplify the whole thing and just mirror what we already support with the crypttab file. -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.14 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBAgAGBQJSEewvAAoJEANOs3ABTfJwzLIQAMfKxeRXkVTklsI6EYYpMQ4X z8F7Mg5Vu79taEZ+e+t71s9U/wNdX6hkCysHQ1qXs8+1IvqxyaFRtdC8HHBSZB0/ CBT6L9v/tH+WOKlEjJesOHPKV1zg2uxRKCHc74bBHdKVJqUrqgB+u42CDsRYq7a0 xgL2Ebvh99a8RoKJEDr+9/Ty+5KgTM0y99z3Wk12JPqAeK+N5z5pnbe6RAW89tG2 f3OjN7Ejf6c+BuJc0S+Eod/2pMV7ccgJJFhKAUQyFYaFfZgG8Wo5sxnUC0SIj508 /MkpVdgrTSsBQt8HxVrlFXm4Zj0M3rA5HsRF77PCPPpJKbU4YAoxkKwMMr6bGEQo 7eeZh3DI/jnpS/QFCDaedDRblWP7rs9e3uso+NDyphq0Th2mg5XiYvhCVsDo5VTX Ys3o78tcfCUyCSdrNhJ+A3hoKxPI9vn1AmA/AnGyI3WMgXiCFJWtGvR6Us5ClTBh iYtZvgZexikpqlZXNN3nBjf6J6hxvtNHFpsAweLrigrMBWrJ4cU4nmrWb2A/ei4G 4h/Z60YQmCKXhymmNQGcZMBpzSGfXdDgLqIbtzdFvvRwPBtG2wuvO+cZaCeF0Dye 3oiOYtoLaIGzfPTvUGbV3FSzAb5Cvjy83qSQMmiDeh5pyAIcBqCpmTUKM4cx4ait xptLc2g2ra1/O59vSyiX =sjhR -END PGP SIGNATURE- ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel

Now you are proposing to add a 'crypttab' option as well. This seems awfully inconsistent to me. OTOH, allowing to give more options on the command line would open the door to more encryption schemes than just LUKS (which I don't particularly care about). I just fear that syntax gets more confusing when allowing many ways to achieve the same goal. >rd.luks.allow-discards= >Allow using of discards (TRIM) requests for LUKS partitions with >the given UUID.

So 1) you are not actually using systemd-cryptsetup-generator, 2) you single out this one option and don't support the rest. signature.asc Description: OpenPGP digital signature ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
