Package: mount
Version: 2.12r-10
Severity: normal
With a disk mounted
type vfat (rw,noexec,nosuid,nodev,noatime,uid=1000,gid=1000,user=jidanni)
nobody including root can get past an invisible umask that makes
chmod 777 666 etc useless.
I challenge you to do a chmod that will allow other users to write a
file anywhere into that disk. It is impossible.
# chmod 777 /cf/tojidanni1/outgoing
# ls -ld /cf/tojidanni1/outgoing
drwxr-xr-x 2 jidanni jidanni 2048 Sep 21 01:43 /cf/tojidanni1/outgoing
Only root and jidanni can write anywhere on that disk. One can chmod
one's head off, no use.
Well, you see one needs some umask in /etc/fstab otherwise all files
become 777 on mount, but one wants to be able to change things
later...
OK, I use
noauto,noatime,user,fmask=133,uid=jidanni,gid=jidanni
but occasionally want to chmod 777 some dirs to allow user proxy to
write.
OK, from now on I will forget user proxy and just use root, as I don't
attempt to understand vfat.
By the way, the next day I mounted the disk on another machine, and
the file timestamps were all in GMT time or something.
I will test if
$ stat bla>bla; cat bla
looks correct when made, but not later when mounted elsewhere...
