Su woes in a gentoo chroot on asus tf700 [SOLVED]

[dwardo]

Hello,

I've sucessfully installed gentoo in a chroot on my asus tf700 (Infinity) and my only woe is that the su command does not work for my "normal" user.

I get a :
setgit: operation not permitted error

I've been googling for a while (>1 week) and have checked that:
* normal user is in wheel group
* permission of /bin/su are correct "-rws--x--x"
* permission of /bin/sh are correct
* modified /etc/securetty to add the pts/[0-9] as those are the tty in android terminal emulator
* ... (read the specific su issues threads on the forums)

I actually see no other chroot on android instructions where people use su (so I guess they stay as root in the chroot...)

I finally went for a strace -o strace.lo su

And when analysing the strace.log file found the first error to be and EACCES when trying to open socket to file /dev/log
Followed by the EPERM error when running setgid32(0)

Turns out on the tf700 /dev/log is not a socket file... but a directory containning 4 things:
crw-rw-rw- 1 root log 10, 28 11 mars 22/13 system
crw-rw-rw- 1 root log 10, 29 11 mars 22/13 radio
crw-rw-rw- 1 root log 10, 31 11 mars 22/13 main
crw-rw-rw- 1 root log 10, 30 11 mars 22/13 events

Could this be the reason the setgid32(0) fails because the preceding acces to /dev/log failed ?

Thanks for any feedback and possible solutions

Regards

Solved...

Well I re-read the stickies and sure enough the answer was in them....
I had missed the "NO nosuid option" for the partition on which su is...

Once that was corrected, all is good !
