There's this cheesy way to get it: # dd if=swapfile bs=4k count=1 | xxd -a 1+0 records in 1+0 records out 4096 bytes (4.1 kB) copied, 6.2589e-05 s, 65.4 MB/s 0000000: 0000 0000 0000 0000 0000 0000 0000 0000 ................ * 0000400: 0100 0000 ffff 0000 0000 0000 f209 fce3 ................ 0000410: 7bc9 486d ac86 5d63 af25 3c99 466c 6173 {.Hm..]c.%<.Flas 0000420: 6853 7761 7000 0000 0000 0000 0000 0000 hSwap........... 0000430: 0000 0000 0000 0000 0000 0000 0000 0000 ................ * 0000ff0: 0000 0000 0000 5357 4150 5350 4143 4532 ......SWAPSPACE2
You can see it is marked as SWAPSPACE2. The label is FlashSwap. Looks like it appears at offset 0x41c. -- Zan Lynx <zlynx@acm.org> [unhandled content-type:application/pgp-signature]
