4 Hiya all,
5
6 Now I feel *really* stupid asking this, but for the life of me I cannot
7 work it out. On two machines here at home I discovered that I can write
8 as a particular normal user to the root partition (/). This also means I
9 can rename /root to /root1 if I want (I just tried), and create / delete
10 files on / too. The strange thing is this does not work for another
11 account (wife's) on the same machine, which seems to have the same
12 permissions. It's almost like / is getting mounted by user "axllent"
13 here. Other partitions that get mounted do not work, just /
14
15 I have checked fstab:
16 /dev/hda3 / reiserfs noatime 0 0
17
18 In /etc/lilo.conf (on one machine that uses it) I have:
19 image=/boot/vmlinuz-2.6.11.10
20 label="2.6.11.10"
21 root=/dev/hda3
22 vga=791
23 read-only
24
25 the permissions of /dev/hda3 are:
26 axllent@workstation ~ $ ll /dev/hda3
27 lr-xr-xr-x 1 root root 33 Aug 15 18:55 /dev/hda3 ->
28 ide/host0/bus0/target0/lun0/part3
29
30 axllent@workstation ~ $ ll /dev/ide/host0/bus0/target0/lun0/part3
31 brw------- 1 root root 3, 3 Jan 1 1970
32 /dev/ide/host0/bus0/target0/lun0/part3
33
34 My groups for this user on both machines are:
35 wheel audio cdrom games cdrw usb users portage
36 &
37 wheel audio at usb users
38
39 My wife who cannot write to / has
40 wheel audio games usb users
41
42 Using Reiserfs3.
43
44 Does anyone have any idea what's causing this, and possibly how I can
45 make / read-only?
46
47 Greetings
48 Ralph
