Please do not misunderstand. I don't vote against lzop. I'm voting for
having that lzip in Busybox as another very effective compressor. I
just wanted to say lzip has it's rights like lzop, another compressor
not so widely used in Linux land ... but they are used!

Thx, for clarifying this. It shows that even compressors not used on
main stream may have there benefits.

Do I tell you something suspicious, if I say I'm using lzop on a
regular basis for the same purpose you mentioned? My Linux kernel even
uses lzop decompression for kernel and intramfs, with noticable
faster startup :)
