Bug#357055: udev: creates fd0, but does not create fd0u* (eg fd0u1722)
I know there may not be many of us using floppies any more, but I'm adding my name to the list for this bug. You probably won't get that many complaints until a recent udev hits stable. I've only just found the problem because I've only recently upgraded to udev 0.093. Floppies are not yet obsolete - they're often needed for flashing BIOS. And fdformat(1) from util-linux absolutely requires the special names, it has no other way to specify the density to which it should format the floppy. I'm quite happy for these little used devices not to be created by default. But for the sake of all those people upgrading from Sarge later this year, at least some of whom are going to have scripted floppy access, I don't think it would hurt to ship an optional config file to create them, with News.debian advising people what to do if they need them.

In case we can persuade you, the attached patch will be needed - it protects
create_floppy_devices against an incorrect array bound check and against
possible buffer overflow resulting from the sysadmin specifying too long
a pathname for /dev.
This could be done better with perl as for write_cd_rules, if only
Mknod.pm were a standard shipped module ...

You are exactly the second person asking about the obsolete devices, I consider this a good enough proof that they are not useful. -- ciao, Marco signature.asc Description: Digital signature
