mkswap lives in sys-apps/util-linux. From util-linux>=2.15.1 on, mkswap will issue a warning when the parameter is a “whole disk”: mkswap: /dev/mapper/swap: warning: don't erase bootbits sectors on whole disk. Use -f to force. This issue is mainly cosmetic: swap areas don’t use the first block on the disk or partition they’re on. Nevertheless, to keep people and bootloaders from trying to boot a swap partition, mkswap usually deletes the first block (or “clears” or “zaps” it, since you can’t delete blocks), but only if there is no disk label or partition table or the like on it. However, if the parameter is not a partition, but a whole disk, mkswap issues the warning above. Since a dmcrypt volume apparently is handled like being a whole disk, the warning occurs there as well. /lib/rcscripts/addons/dm-crypt-start.sh should use “mkswap -f” to create swap volumes. Currently, line 34 says: : ${pre_mount:='mkswap ${dev}'} Insert a -f there, and everything should be fine. Oh, and while you’re at it: Please show some love for bug #257556 as well. It’s a small patch that will make multi-dmcrypt-volumes users happy. Workaround for users: Add pre_mount='mkswap -f ${dev}' after the “source” line of your swap definition in /etc/conf.d/dmcrypt.
