During the Full Updates phase, new hardware support will be provided at the discretion of Red Hat - and thus CentOS - via Update Sets. Additionally, all available and qualified errata will be provided via Update Sets (or individually and immediately for Security level errata.) Update Sets normally will be released 2-3 times per year, with new ISOs released as part of each Update Set. In the x.y numbering scheme, the .y is the number of the Update Set. (1)
During the Maintenance updates phase, only Security errata and select mission critical bug fixes will be released. There will be few, if any, Update Sets released upstream. (2)
Only PAE-capable CPUs are supported, see http://wiki.centos.org/FAQ/CentOS6#head-d31388203ee81d3a47cb97bfc1c8206c3de85095 (3)
Logical CPUs are equivalent to cores/virtualCPUs, so a dual-core (non-hyperthreading) CPU is counted as 2 logical CPUs and a single hyperthreading CPU is counted as 2 logical CPUs for purposes of calculating total CPUs. (4)
While 1EB is nominally supported under ext4, CentOS' upstream has not backported a needed patch to the ext4 tools permitting manipulating such partitions as of the update at CentOS 6.3. It is possible to use partitions created using third-party distributions' later e4fsprogs tools. [https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Storage_Administration_Guide/newfilesys-ext4.html General information upstream] (5)
UEFI and GPT support required for more than 2TB boot LUN support. See [https://access.redhat.com/kb/docs/DOC-16981 this] upstream information (6)
The x86 "Hugemem" kernel is not provided in CentOS 6. (7)
The initial 6.0 low end of a nominal 128M minimum is probably overly optimistic, even for a TUI install. Starting with the 6.1 point update of CentOS 6, dependency solving is a massive RAM hog (8)
bootable p2v- and v2v-ISO-images are provided starting with 6.3, see also http://wiki.centos.org/Manuals/ReleaseNotes/CentOS6.3#head-2e2994dcc0edf71ebb47daa0b808b9d83f91f7b2 (9)
Recommended for text mode only; graphical modes require 1GB (10)
since 6.5 (11)
Firefox, Thunderbird and Office-Suite will be updated during product lifecycle (12)
Openoffice is discontinued in 6.3 (13)
