Нет, можно воспользоваться возможностью portage устанавливать пакеты не в корневую систему. Изначально эта функция предназначалась для сборки минимальных версий gentoo и для кросскомпиляции, однако сгодится и в такой ситуации.

Грузимся с LiveCD или любого работоспособного Linux (с подходящей архитектурой, для починки x86_64 дистрибутива надо грузиться с x86_64 системы).
Качаем stage3 и распаковываем в сторонке, по желанию можете воспользоваться работающим дистрибутивом Gentoo у товарища.
Монтируем корневую ФС убитого дистрибутива в каталог, расположенный внутри распакованного stage3, например в mnt/broken
Говорим emerge ставить пакеты внутрь сломанного дистрибутива:

ROOT="/mnt/broken" emerge -1 my_package_name

Пакет будет установлен по всем правилам, с записью в world (если не была указана --oneshot).

Environment

• Red Hat Enterprise Linux 7
• Red Hat Enterprise Linux 6
• Red Hat Enterprise Linux 5
• Red Hat Enterprise Linux 4

Issue

• Is any virus protection software needed for Red Hat Enterprise Linux?
• Does Red Hat provide any-virus protection software?

Resolution

• Red Hat does not provide anti-virus software.

• Red Hat does provide a high level of security in the operating system and packages that we distribute. As security issues are discovered in various applications, Red Hat provides updated packages in a way which keeps potential risk to a minimum.

• For information on Red Hat's policy on backporting security fixes see "Security Backporting Practice".

• For information on Red Hat's policy on product security see "Product Security Overview".

• Red Hat Enterprise Linux also includes a set of technologies which can greatly reduce the chance of Linux-specific exploits. One example found in Red Hat Enterprise Linux 3 and higher versions is ExecShield, which helps to eliminate memory buffer overflow exploits . Another example available in Red Hat Enterprise Linux 4 and above is SELinux, which is an implementation of a mandatory access control mechanism.

• There are also some good security practices to follow to make sure a system is safe:

  • Keep a system updated so all patches and security updates are installed. A subscription to Red Hat Subscription Management (RHN) will help keep a system updated.
  • Run a local firewall on the system, such as iptables, to block any unused ports.
  • Do not login as the root user unless needed. Use sudo and log in as a non-root user.
  • Do not execute any untrusted code on the system, especially as the root user.

• Enable Security-enhanced Linux (SELinux). This mechanism is in the Linux kernel, checking for allowed operations after standard Linux discretionary access controls are checked.

• The following guides give detailed information on configuring a particular version of Red Hat Enterprise Linux from a security point of view :

  • Red Hat Enterprise Linux 7
  • Red Hat Enterprise Linux 6
  • Red Hat Enterprise Linux 5
  • Red Hat Enterprise Linux 4

• There are third party anti-virus programs available from the Linux community, that protect other Windows clients on the network from viruses. They scan the files looking for Windows virus signatures. Thus, for example, a samba server serving files to Windows clients could have the anti-virus running on the samba server scanning these files

  • One example of such an anti-virus is ClamAV. Clam AntiVirus is available from http://www.clamav.net/ but is not distributed or supported by Red Hat.
  • The article Is fanotify supported in Red Hat Enterprise Linux? provides insight into real-time filesystem scanning and usage by various anti-virus software vendors.
