dougm 5a521a24c0 swap_pager.c reserves 2 blocks for a bsd label. Change that 2 to the ... expression howmany(BBSIZE, PAGE_SIZE), where BBSIZE is the size of the boot block area. That can be less than 2 if PAGE_SIZE is big. swapon(8) has an option to trim (delete) all the blocks of a device at startup. However, if the first of those blocks is a bsd label, then trimming those blocks is destructive. Change swapon to leave the first BBSIZE bytes untrimmed. Update manual pages to reflect changes in how swapon and how it may be used, espeically in association with savecore.
