Hi there, i was using FC2 before. I have a very slow machine (Celeron 600 on SiS630 with 256MBs of RAM) so In FC2 i stopped some services, like sendmail, iptables(my modem does not work under linux so i do not use it for internet), isdn, ntfs, network etc. as they are not needed for a single, no-internet PC. With these servies stopped FC2 took 1/2 of the booting time. now i have a fresh installation of FC3 and it takes VERY-LONG time to boot as compared to FC2. Even after i have stopped the same services (same as FC2 which i do not need), it still takes VERY LONG time to boot. actually 2 services in the boot-process: 1.) starting: udev 2.) initializing hardware: storage network audio done take VERY-LONG TIME. other services are fine in comparable to FC2 boot-up time-consuming process. In fact these 2 services were NOT PRESENT on FC2. they only appear in FC3 ( and they are frustrating services). NOW ca! n anybody tell me PLEASE -- what are the functions of these 2 services and -- how can i remove them (if and only if they are not useful)
As far as I know, FC2 and below used static /dev entries, whereas FC3 and above use dynamic ones. Your /dev tree gets populated at boot time using udev.
Personally - my experience is like yours - the Linux boot up procedure is slow enough as it is and I would prefer going back to static /dev entries if it means faster booting but I'll just go with the times.
For my server I don't mind so much, as it's never rebooted, but my laptop is dismal.
Anyway - I think I've partly answered your question. As to why using udev is better or why we went to it - I don't know. For me it's more of a hindrance than a benefit, but I probably don't understand it fully.
Regards, Ed.
