While starting a user mode linux image with an encrypted swap partition with this command line : earlyprintk ubda=/home/tfoerste/virtual/uml/gentoo_unstable ubdb=/home/tfoerste/virtual/uml/swap_gentoo_unstable eth0=tuntap,tap1,7a:cf:14:11:67:01, mem=256M con=pts con0=fd:0,fd:1 root=98:0 I get during startup this message: * Setting up dm-crypt mappings ... * crypt-swap using: -c aes -h sha1 -d /dev/urandom create crypt-swap /dev/ubdb ... [ ok ] * pre_mount: mkswap ${dev} ... mkswap: /dev/mapper/crypt-swap: warning: don't erase bootbits sectors on whole disk. Use -f to force. I found a lot of links related to the "Use -f to force" but always for different environments and often quiet old. /me wonders whether this is a bug or only a cosmetic issue. Reproducible: Always
FWIW at an unstable Gentoo I don't see this issue : * Setting up dm-crypt mappings ... * crypt-swap using: -c aes -h sha1 -d /dev/urandom create crypt-swap /dev/ubdb ... [ ok ] * pre_mount: mkswap ${dev} ... [ ok ] [ ok ] * Checking local filesystems ...
