I quick test with a PowerPC kernel and the normal vmlinux image reveals that this is nonsense.=20 -rwxr-xr-x 1 root root 2766490 2003-09-27 22:29 vmlinux -rwxr-xr-x 1 root root 1149410 2003-09-27 22:29 vmlinux.gz -rwxr-xr-x 1 root root 1062999 2003-09-27 22:29 vmlinux.bz2 This is a 86411 bytes or 8.1% reduction, seems significant to me... Granted, it takes 9 times as long to decompress the kernel and ca. 900kb more memory but considering an embedded DSL router I'm working with which has 16MB RAM but only 4MB Flash this is certainly worth it. At least when the target is an embedded device. --=20 Servus, Daniel --=-/PpnUPVp30c3q8EvrIyV Content-Type: application/pgp-signature; name=signature.asc Content-Description: Dies ist ein digital signierter Nachrichtenteil -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) iD8DBQA/kSZjchlzsq9KoIYRAhRQAKClhBbiqWoA+1lfWSRCcP12wDcBPACg25Fq Y1gaUl0YmtCTvTWkpGY+XoM= =9yAp -----END PGP SIGNATURE----- --=-/PpnUPVp30c3q8EvrIyV--
