This -information is determined automatically by mkswap if it is omitted. Block -counts are rounded down to pages of 4 kB each. Only block counts equal to -or greater than 40 and equal to or less than 131072 are allowed. Block -counts greater than 130752 are (silently) rounded down to 130752. - -As Nick Holloway explains, the actual maximum for each swap file/partition -is: -.RS -(4096 - 10) * 8 * 4096 = 133890048 bytes = 130752 blocks = 127.6875 Mb -.RE -This is because a single page is used to hold the swap bitmap at the -start of the partition, where each bit is a single 4K page. The reason -for the -10, is that the signature is "SWAP-SPACE" -- 10 characters. - -.B mkswap -can also set up swap files, although the file has to be created first.
