/etc/cron.daily/standard: the df issue again
Hi,
/etc/cron.daily/standard, as shipped with the cron package, features
# Get a list of the (potential) ext2 l+f directories
lflist=`df -P --type=ext2 |awk '/\/dev\// {printf "%s/lost+found ", $6}'`
Off course, this fails on the Hurd, and gives an - imho annoying - message
df: cannot read table of mounted filesystems
If I understood the discussions about this issue correctly, it is
currently impossible to get a list of mounted "real" filesystems.
In http://lists.debian.org/debian-hurd-9912/msg00126.html , Marcus Brinkmann
wrote:
"What we could do is to write a database server where filesystems can
register themselves if they want."
Has any progress on this been made? Would this be the right way to
do it, or have opinions changed?
As a quick fix, I've seen people suggesting to make /var/run/mtab
a symlink to /etc/fstab. However, I've got this
/dev/hd0s1 / ext2 rw 1 1
/dev/hd0s5 none swap sw 0 0
as my fstab. df fails on `none' as a mountpoint, when using this as
mtab. Making this symlink does not give me a warm and fuzzy feeling.
Anyway, about the standard script, I hacked up this patch:

I would love to get rid of the locate-call, but don't know how.
I'm considering filing a bug against the cron package. Would that be
appropriate?
Bye,
