i've received two requests for the "nofail" option. the doc for the
option is a bit ... terse ... so it's hard to guess at the overall
intention.
(1) ignore ENOMEDIUM like:
sys-utils/mount.c could be updated to do:
case ENOMEDIUM:
if (uflags & MNT_MS_NOFAIL)
return MOUNT_EX_SUCCESS;
warnx(_("no medium found on %s"), src);
break;
this is for cases like cd/dvd drives which happens to have no disk loaded.
(2) ignore unknown fs types. e.g. when a kernel config/module is missing
support for the requested filesystem type. so a fstab entry like:
..src.. /mnt/foo somefs defaults,nofail
rather than error out with:
mount: unknown filesystem type 'somefs'
it would just issue a warning like it does for other nofail options.
if we go this route though, how far should we take it ? should we make
all failures when nofail is active the same ? i'm kind of leaning that
way ...
