Public bug reported:
With TMPTIME set to anything other than 0 in /etc/default/rcS the init
script has to find files to remove rather than simply wiping /tmp. This
fails to remove symbolic links.
lrwxrwxrwx 1 1001 1001 12 Mar 20 02:01 test2.jpg -> download.jpg
lrwxrwxrwx 1 1001 1001 3 Mar 20 02:04 beh -> meh
$ file beh
beh: broken symbolic link to `meh'
$ file test2.jpg
test2.jpg: broken symbolic link to `download.jpg'
My TMPTIME is set to 3 but these two files are well over a month old.
The script uses find but this seems to find the files no problem:
$ find . ! -type d 2>&- | egrep "beh|test2"
./beh
./test2.jpg
Tests using "find . ! -type d -delete" show "find" removing symbolic
links both working and broken.
My syslog does show this during boot:
kernel: [ 723.500519] type=1302 audit(1429024710.712:73): item=0
name="/tmp/beh" inode=221577 dev=08:05 mode=0120777 ouid=1001 ogid=1001
rdev=00:00 nametype=NORMAL
This seems to be updating the atime, and the atime is used in the
expression:
TEXPR="-mtime +${TMPTIME} -ctime +${TMPTIME} -atime +${TMPTIME}"
The result being that symbolic links will, apparently, never be removed.
I have no idea what is updating the atime for these symbolic links or
why it is being audited. It's nothing I have intentionally set up on
this system. It may be that the script is not at fault here but whatever
package is updating the atime on these files.
A temporary solution would be to have a separate expression just for
symbolic links ignoring the atime, but this may not be what a user
wants. However: I can think of no good reason why anyone would need a
symbolic link hanging around /tmp for longer than the TMPTIME.
