After an upgrade a while ago, autofs was no longer able to mount ntfs
(ntfs-3g) filesystems. I only tracked this down today, and this is due to
autofs using the "-s" mount option although it's not supported by ntfs.
Specifically, this map entry:
dosc
-fstype=ntfs,iocharset=utf8,codepage=850,shortname=mixed,utf8,dmask=077,fmask=177
:/dev/disk/by-label/WIN7
can be mounted manually:
mount -t ntfs
-oiocharset=utf8,codepage=850,shortname=mixed,utf8,dmask=077,fmask=177
/dev/disk/by-label/WIN7 /mnt
but trying to enter "dosc" gives "bash: cd: .../dosc: No such file or
directory".
strace'ing autofs reveals the reason:
[pid 4237] execve("/sbin/mount.ntfs", ["/sbin/mount.ntfs", "/dev/sda1",
"/fs/dosc", "-s", "-o",
"rw,iocharset=utf8,codepage=850,shortname=mixed,utf8,dmask=077,fmask=177"], [/*
19 vars */]) = 0
the -s option doesn't exist for mount.ntfs - the mount manpage documents
that -s isn't supported by all filesystems (and in fact, might be
supported only by nfs):
# "/sbin/mount.ntfs" "/dev/sda1" "/fs/dosc" -s -o
rw,iocharset=utf8,codepage=850,shortname=mixed,utf8,dmask=077,fmask=177
ntfs-3g: Unknown option '-s'.
I looked at the autofs manpage, but it wasn't immediatelly clear why it
would add -s by default, or whether this is overridable. It definitely
worked in the past, so this must be a relatively recent change.
