==Future Change Considerations==

Future changes to the objective will/may include:

* EFI shell, gdisk, parted not included.  More appropriate in LPIC-1 update.

* lighttpd would have been too much coverage of web services.  Perhaps reduce Apache next revision to make room.

* host level IDS (tripwire, AIDE, etc) to be covered in future LPIC-1.

* sieve and maildrop to be considered in a future update.

* SAN, AoE, and FCoE to be considered in a future update.

* encrypted file systems are covered in-depth in LPI-303 exam.

* mention of DANE

* more SSSD

* drop lilo, (consider U-boot and other non-x86 topics)

* introduction (or more) to FreeIPA

* drop SSLCertificateChainFile...deprecated as of [[https://www.apachehaus.com/index.php?option=com_content&view=article&id=119&Itemid=104 March, 2014]]

* add coverage of mod_security and mod_evasive to Apache HTTP (maybe as a separate topic: Web Application Firewall)

* add coverage of a higher-level firewall package like firewalld or ufw

* add xzImage to kernel image names if it ever gets used

* update 204.2 (adjusting storage devices) to include NVMe and AHCI (with IDE/PIO coverage) - make Bryan do it? :)

* update Samba section to include version 4 and drop version 3

* be more specific on which features/tech for encrypted file systems (and/or add more content)

* Include sieve filters and reconsider procmail
