All of a sudden I got the following error when trying to emerge --sync:
rsync: ERROR: cannot stat destination "/var/tmp/tmp7QWkJ5": Permission denied (13)

strace -fp emerge --sync reveals:
...
open("/var/tmp/tmpSaIEJs", O_RDWR|O_CREAT|O_EXCL|O_NOFOLLOW, 0600) = 3
fcntl(3, F_GETFD) = 0
fcntl(3, F_SETFD, FD_CLOEXEC) = 0
close(3) = 0
stat("/var/tmp/tmpSaIEJs", {st_mode=S_IFREG|0600, st_size=0, ...}) = 0
chown("/var/tmp/tmpSaIEJs", 250, 4294967295) = 0 /* 250 is portage */
...
[pid 31338] stat("/var/tmp/tmpSaIEJs", 0x7fffade5ad10) = -1 EACCES (Permission denied)
[pid 31338] write(2, "rsync: ERROR: cannot stat destin"..., 82rsync: ERROR: cannot stat destination "/var/tmp/tmpSaIEJs": Permission denied (13)) = 82
...

It seems (I believe) that tmpdir creation is done by root and accessing it is done by user portage running rsync.
I'm somewhat clueless how to find the culprit.
Am I alone with this problem? Hints anybody?

Cheers
Hajo

Maybe the sticky bit got lost. Check ls -la /var/tmp/ .

Thank you, when I moved my /var/tmp to a separate partition I forgot to set the permissions to the default 1777.

Thanks massimo - chmod 1777 did the trick :)
