So there is no filesystem issue. Errors sometimes result in the
partition being remounted readonly.

Stroller has a point, read his post. As the mounted partitions list is
inside /proc, if you forgot to mount that, then maybe the ebuild can't
just find out /boot is actually mounted. There are probably other things
that might not work if you don't mount these partitions, so just to be
sure, check if you did that :-)

writing (and executing)

  export DONT_MOUNT_BOOT

in the shell should be enough.
