How can you tell without access to the kernel config?

I got the impression that if I don't use meetme (what's that for?) or another feature which people manage by without then I don't need all this at all. > > In addition to that, if you need to mess with kernel module building, > you'll find that with Debian things actually work, whereas with Centos > you have to fight the system harder to make them so. I'll see. Thanks. When I start using this knowledge for my workplace I'll have to do it on CentOS anyway (it's our SOE now, by my own decision) so I'll have to deal with it anyway. > >> >> > >> > See also http://docs.tzafrir.org.il/#_kernel_configuration >> > >> > I would also recommend: >> > >> > 1.

With Debian hosting at least on one place (I think Spry, the parent of VPSLink) I got stuck with an old Debian on a Virtuozo VPS which I can't upgrade without just installing the machine from scratch (I know Debian supports in-place upgrades, but the virtual host setup won't allow this). > >> >> > 2.

Are you saying that once I decide to go with Asterisk I also have to keep close chase of their latest release in order to have it supported (i.e. bug and security fixes)?
