Hello,
This is a modified repost from SELinux mailing list and
repeated here only because I was not sure where this message
is to be posted since it is a FC5-T3 issue.
I have read previous posts regarding creating swapfiles
under SELinux and supposedly a fix was done but the circumstances
of this error is different. SELinux refuses to allow a relabel via mkswap.
The steps to create a swapfile is:
1) dd if=/dev/zero of=/swapfile bs=1024 count=<SWAP-SIZE>
1.5) New step: chcon -t swapfile_t /swapfile
2) mkswap /swapfile
3) swapon /swapfile
4) Add entry to fstab
A new security context of swapfile_t was added in FC-T3, and
supposedly added to mkswap as well. I have have the latest YUM
development updates for FC5-T3.
Doing step (1.5) above results with a "relabel" Permission denied:
> mkswap /swapfile
mkswap: unable to relabel /swapfile to swapfile_t: Permission denied
