https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D276645 Bug ID: 276645 Summary: Fix for swapon overwriting Linux swap header Product: Base System Version: 14.0-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: rbranco@suse.com The Linux swap partition uses a 4096-byte header that holds the label & UUI= D. You can see the structure here: https://github.com/util-linux/util-linux/blob/master/include/swapheader.h The problem is thus how to prevent FreeBSD from overwriting the header. It turns out there's a neat way to do just that with GEOM using the gnop system tool. This PR modifies swapon to automate this process, which also works with /etc/fstab. This will benefit dual-boot installations and also live-CD's. Fix: https://github.com/freebsd/freebsd-src/pull/1084 --=20 You are receiving this mail because: You are the assignee for the bug.=
